Groundspeed - Redexim Verti-Drain 7516 Operator And Parts Manual

@ From 90 to 75 degrees means more "kick action". This is advised for solid tines, depending on
ground conditions, tine size and customer requirements.
@ The angle of 90 degrees means that the tines penetrate perpendicular into the ground. This is only
true if the machine is correctly set, see fig.1. If this isn' t correct a push force F, see fig 5. is applied,
which can seriously damage the machine.
@ The length of the draw rod assembly should be 560.00 mm (22.050"), which can be set by the
calibrating shimms, see the spare part page

7.0 GROUNDSPEED

The groundspeed determines the hole spacing D in the drive direction, see fig.6. The VERTI-DRAIN
doesn' t need a creeper gear, however if the customer wants a close hole spacing, the groundspeed
should be low enough, which depends on the tractor.
The gearbox has standard three different gearsetting, resp 1,2 an 3. The higher the setting, the more
rev' s on the crankshaft.
The input speed R on the PTO may be maximum 500 rpm. When stones or rocks are expected, the input
speed should be lowered.
With heavier tines or attachments, the tineholders may start to float. Lower rpm' s at that time, before the
tineholders start to turn upwards.
In Fig.6., a graph is drawn in which the relation between the groundspeed, the gear setting and the hole
spacing is given. If the tractor groundspeed is known at 500 rpm' s of the PTO, the hole spacing can be
determined at different gearbox settings.
@ If the machine is not set correctly behind the tractor, see fig.1., different angles at the PTO may
cause vibration into the drive line of the VERTI-DRAIN. This vibration can hurt the machine and
also the performance of the holes in the ground.
@ If the gear box setting is hard to shift, rotate the crankshaft a little till the shifting is possible. You
can use the "Combi-Tool" for easily rotating the crankshaft.
@ If the PTO shaft is incorrectly fitted (too long or too short), extra forces are applied to the input shaft
of the gearbox. Damage may occur.
* When the gearbox is shifted, shut off the tractor engine
